GoKawiil3M Hid Evidence That PFAS 'Forever Chemicals' Were in Human Blood for Decades
ProPublica reporter Sharon Lerner uncovered internal 3M records showing the company knew as early as the 1970s that PFAS compounds used in nonstick coatings, food packaging and stain-resistant products had entered people's bloodstreams worldwide. Rather than disclosing this, 3M kept the findings confidential for decades, according to a former company scientist who spoke with Lerner.
